“Ingenious and powerful instruments have been devised, which reveal wonders otherwise unimagined, and the end is not yet.” Herbert A. Howe, the first professor of astronomy at the University of Denver.
Chamberlin Observatory was the vision of 3 men: Herbert A. Howe, Denver businessman Humphrey Chamberlin who pledged $50,000 to build and equip the facility, and local architect Robert S. Roeschlaub.
It was commissioned for the University of Denver in 1888. Construction on the red sandstone Richardsonian Romanesque-style building, with an imposing silvery dome of galvanized iron began in 1890. The astronomical design was done by Howe, featuring a Clark-Saegmuller refractor, a 26-foot-long telescope made from steel, cast iron, and brass, which holds a 20-inch doublet lens constructed by Alvan Clark & Sons. It first saw light in 1894.
The observatory was built in the era of steam trains and horse-drawn wagons. The red sandstone was quarried from Lyons, Colorado, and wood from Oregon timber. The dome was engineered to rotate 360°.
Owned and maintained by the University of Denver, Chamberlin Observatory has been home to the Denver Astronomical Society since 1949. It was listed on the National Register of Historic Places in 1980. Today, the Observatory inspires the next generation of astronomers by serving as an educational facility for students and the public. They host regular public viewing nights, where visitors can see celestial objects like the moon, planets, and nebulae.
It stands as strong as ever as a testament and symbol of scientific inquiry. The beautiful view of the heavens belongs to a bygone era, but still provides the ability to extend our vision to help us better understand the universe we live in. đź–¤
